WIRE-CUTTING DEVICE FOR GUNS.

. Application filed October 17, 1921. Serial No. 508,302.

T 0 all whom it may concern:

Be it known that I, MICHAEL Haas, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Tire-Cutting Devices for Guns, of which the following is a specification.

An object of this invention is to provide a wire cutting device adapted to be removably secured to rifles, muskets and similar arms.

Another object is the provision of means by which a wire cutting device, attached to certain forms of tire arms, may be employed for cutting barbed or other wire structures forming barriers or entanglements.

A third object is the provision of means whereby the cutting elements of a wire cutter, adapted to be attached to certain fire arms, are automatically causedto return to normal open position immediately after severing the wire.

These and other objects are attained by the novel arrangement and construction of parts, hereina'l'ter (lGSCI'lbBCl and shown in the accompanying drawing, forming a material part of this disclosure, and in which Figure 1 represents the forward end of a rifle barrel and hand grip with the wire cutter shown in elevation.

Figure 2 is a rearedge view of the cutter.

Figure 3 is a rear side elevational View showing the cutting elements in normal or open position.

Figure 4- is a fragmental sectionalyiew through the base, showing the means of attachment and with the securing clamp in locked position.

Figure 5 is a slmilar View showlng the securing clamp in free or unlocked position;

Figure 6 is a rear side elevational view, showing the cutter in the position assumed at the moment of separating the wire.

Figure 7 is a sectional view taken on the line 77 of Figure 1.

Referring to the figures in detail, the numeral 10 represents generally a rifle comprising a barrel 11, a sight 12, a hand grip 13, and a band 14 to which is attached a sling 15.

Secured to the forward end of the hand grip 13 is a ferrule 16 on which is integrally formed a projecting T shaped lug 17 adapted to slidably engage a transverse T shaped slot 18 extending partially through the lower portion of a rigid member 20 forming the base element of the cutting device.

The upper portion of the element 20 is curved concentrically with a central opening 21 and is provided with teeth along a portion of its peripheral face, forming in effect a fixed segmental gear 22.

Adjacent the flat side of the element 20 is a plate 23 pivotally secured therewith and an extending portion, semi-circular in outline, is provided with a radially disposed notch 24.

A disc 25, pivotally engaged adjacent the plate 23, is provided with gear teeth 26 upon a portion of its peripheral face, these teeth being adapted to mesh with the teeth in the segment 22.

A retaining link 27 having rounded ends, is provided with spaced openings alignable with similar. openings provided through the elements 20, 23 and 25, these openings being receptive of the retaining pivots 28.

With the cutter elements in normal position, as shown in Figure 3, a radially disposed notch 30 is formed through the teethed disc 25 registering with the notch 24 of the plate. 23.

A recess *31 is counterbored ment 22 adjacent the plate 23 and encloses a coiled torsion spring 32, having angularly bent ends 33 and 34 engaging in holes in the elements 20 and 23, thus providing means by which the cutting elements are automatically maintained in normal position.

To guard against accidental loss or displacement of the cutter, a bolt 35 passes through an opening in the base 20 into the T slot 18 and, abutting against the end of the T element 17, prevents the removal of the cutter. When it is desired to remove the cutter, a push stud 36, passingthrough the base 20,. is depressed and being fixed at its lower end to an offset finger 37 integral with the bolt 35, carries the finger downward, opening the T slot and permitting the cutter to be removed.

An enlarged head 38 is provided on the upper end of the stud 36 and is slidably operable within a recess 39 and held in outward position by a coiled spring 40 acting between the underside of the head 38 and the bottom of the recess 39.

In operation, the wire cutter beingattached to the rifle as shown in Figure 1 may be considered as in normal position; the

into the ele-- cutting jaws 24; and 30, being in alignment, are receptive of a wire.

A forward thrust of the rifle causes the cutters to move backward-An the direction shown by the arrow in Figure lby the resistance of the wire against the cutting Jaws. V

The lower base portion being fixed, and provided with a toothed segmental portion, having a central pivot about which the moving elements rotate, while a disc cutting jaw, pivotally engaged 'with the plate cutting jaw and in mesh with the fixed segment, is caused to rotate at a greater speed than the plate jaw, this dilference in speed, forcing the cutting jaws to pass oneanother, severing the wire held between'the cutting jaws.

Immediately upon the severing OftllG wire, the cutter returns to its normal position by the action of the spring enclosed within the cutter. V 1

The foregoing disclosure is to beregarded as descriptive and illustrative only, and not EIS'l'GSlDliChlVG or limitative of the invention,

of which obviously an'embodiment may be constructed including many modifications without departing from the general scope herein indicated and denoted in the appendedclaims.

, Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is V 1. In a wire cutting device, the combination of a fire arm, a ring ferrule secured thereon, a tongueintegral with the ring, a supporting frame comprising an extending plate, gear teeth formed partially around said plate, a base having a, T .slot adjustable means in the slot engaging the tongue, a plate pivoted to said body, a'disc pivoted on said second plate, said disc having teeth in mesh with the teeth in the first named plate, and means formed co-operatively in said second plate and disc fo'rseveringawire. 7 r V 1 2. In a wire cutting device, the combina tion of a supporting frame having a toothed element, a plate pivoted thereto, said plate having an arcuate extending end containing a notch, a disc'pivoted on said plate, gear teeth formed partially around the disc, said disc containinga notch approximately opposite said teeth, the teeth meshing with the toothed element of the supporting frame, and

a pivoted strap engaging the geared elements.

3. In a wire cutting device, the combination ofaremovable supporting frame having gear teeth formed on its outer arcuate end, a disc having gear teeth, a notch in said disc adapted to engage a wire, a plate adjacent said supporting frame and notched discand means for holding said disc in meshed engagement with the gear teeth or" said frame.

4. In a wire cutting device, the combination of a removably supporting frame, gear teeth formed on itsiouter end, a plate pivoted adjacent the-frame, a disc pivoted to said plate and having teeth engageable with the teeth of said supporting frame, curved bottomed notches formed through said plate and disc in register with each other and adapted to receive awire when in fire arms, the forward thrust of which ini tially operates the cutting device.

5. In a wire cutting device, operably attached to fire arms, said cutting device consisting of a pair of riveted adjacent plate elements, said: plates having annular portionsprovided with notched recesses forming cuttingjaws adaptedtoreceive a wire therein when in open or normal position, one of said plate elements being a disc hav-. ing a toothed segmental portion adapted to mesh with a similar toothed segmental gear integral with a base frame member, the other plate element having a lower portion pivotally engaged at the center of the segmentalgearbase, rotating therewith and carrying with it in planetary motion the toothed cutting disc, said disc operating from a point of rotation diiierent from that of the adjacent cutting element causes the said cutting jaws'to overlap or pass onev another, thus severing the wire therebetween. In witness whereof I afiixr my signature;

, MICHAEL HRAB.
